TPower i45 overclocking controls are nearly identical to Biostar’s less-expensive TP45 HP, but with slightly greater CPU core voltage range.

The biggest advantage the TPower i45 had over its cheaper sibling is the ability to support our Crucial Ballistix memory at DDR2-1066 CAS 5-5-5-15 and 2.2 volts. Then again, nearly every motherboard save for Biostar’s cheaper TP45 HP can do this.

All of the important memory timings can be adjusted. But disabling “Configure by SPD” will force builders to manually choose every timing, since an “Automatic” value for individual settings doesn’t exist. We were fortunate enough to get away with BIOS defaults when setting our main timings to 5-5-5-15.

A “Clock Gen” sub-menu provides PCI Express clock and several skew plus driving strength controls.

The TPower i45 Voltage sub-menu looks identical to that of the TP45 HP, but allows a greater range of CPU core settings.

Ten profiles store custom BIOS configurations, just in case a user is forced to use the “CLR_CMOS” jumper following a missed boot.
